September 20th 2026: I was driving my 2024 Chevrolet Trax up a grade (Mountain) approximately 11AM, Driving Normally at Highway speeds, normal highway conditions, temp outside was close to 100 Degrees Fahrenheit, suddenly with no warning half way up the mountain the car lost power, check engine light turned on (Engine Power Reduced) came on, I had no option but to pull over on the highway with only 41,500 miles on the odometer. Being over 200 miles away from my home I felt devastated. Made an appointment the next morning to have the car checked out by the Chevrolet Technicians at the dealership, they stated the Turbo completely failed, the part was on a slight back order they pushed through and it took a week to get this repair done. Previous to the Turbo failing, approximately at 36,000 Miles on the odometer on or about January of 2026: I get in my Trax and the A/C will not blow cold air, took it in for service at the same dealership come to find out the A/C condenser failed or ruptured leaking Freon, I paid $1,800.00 on an expense out of pocket that was not covered by any warranties.I Even purchased the extended warranty when I bought the car with 0 miles in November of 2023. Previous to the A/C condenser failing with no warning what so ever, on November 2025 I go open my car and the remote unlock feature does not work due to a completely dead battery car would not start or open. The car had to be towed to the dealership because after they jump started it the transmission started clucking really hard when shifting into Drive. The culprit according to Chevrolet Dealer Service Advisors was just a dead battery(covered by warranty) , yet the car gave no signals of a dying battery.after picking up Car I noticed rough idle and performance after this incident, I took it back to get checked out the same day and they could not “replicate” the symptoms, they stated that they can only fix it when the car blows up since it wasn’t showing any Check engine lights.

Over the last 18 months the check engine light has come on multiple times while driving. Each time the check engine light came on, the vehicle was taken to the dealer. I was initially told by the dealer that they could not figure it out but to bring the car back if it happens again. Each time after taking the vehicle to the dealer for the check engine light, the dealer added oil to the vehicle. On one occassion the vehicle decelerated suddenly while driving. I reported the incident in a survey that I received from the dealer after an oil change. In April 2026, the dealer said that the engine appears to be consuming too much oil and an oil consumption test is needed. In September 2026, the vehicle was taken to the dealer after the check engine light came on and the dealer stated that an engine rebuild is needed and GM would be contacted.

The check engine light illuminated on my 2024 Chevrolet Trax at 36,883 miles. An authorized Chevrolet dealer, Advantage Chevrolet of Bridgeview in Bridgeview, Illinois, diagnosed a failed evaporative emission canister purge pump and replaced it on August 6, 2026. I paid $729.46 out of pocket. I am filing this complaint because General Motors has already identified this exact part as defective and extended warranty coverage for it — but not for my model year. The part installed in my vehicle, shown on my invoice, is GM part number 25207556. That part number is listed by name in the Parts Information table of GM Special Coverage bulletin N242484740, which identifies four interchangeable evaporative emissions canister purge pumps: 12741165, 12741163, 25207556, and 12726033. That bulletin extends coverage on this component to 15 years or 150,000 miles for the 2022 Chevrolet Trax, 2022 Silverado 1500, 2022-2023 Blazer, and multiple Buick, Cadillac, and GMC models. A prior program covered 2020-2021 vehicles. My 2024 Trax failed with the same part number GM covers for fifteen years on the 2022 Trax. The failure occurred at 36,883 miles — five days after my 3-year bumper-to-bumper warranty expired on August 1, 2026, based on an in-service date of August 1, 2023. The failure illuminates the malfunction indicator lamp, which masks any other diagnostic trouble code that may set behind it, increases evaporative hydrocarbon emissions, and causes automatic failure of Illinois OBD-based emissions inspection. GM has now issued purge pump coverage extensions twice, for 2020-2021 and again for 2022-2023 vehicles. The same component is failing on 2024 vehicles at comparable mileage. I believe the defect extends to the 2024 and later model years and that coverage should be extended accordingly.

My 2024 Chevy Trax’s engine (1.2L turbocharged I3 engine) went out while driving on the expressway (about 70mph) in the middle to left lane. I had to come to a complete stop and safely and immediately get my car on the left shoulder without injuring myself or others around me. My own safety was severely at risk as I was as close to the dividing wall on the left side as I possibly could be but cars are racing through right next to me. Another safety risk to be added is I was dropped off in the most sketchiest plaza and stranded from 12/1am-3am. I was left to lock myself in my non operating vehicle in a country I do not reside in. Issue was confirmed the following day or two at a dealership I got the car towed to, they found a hole in my engine block due to a rod. And all documents can be provided. Police and blocker trucks were unable to arrive to the scene for 40+ min and the car was fully investigated by GM. There were no engine lights or warnings on the Chevrolet app or car dash. The only thing I can mention is on my last documented oil change, the oil was low due to high consumption, no leaks were located. Dealership also found the fuse box blown, I assume hot oil gushed all over my wire harnesses or the oil switch flipped the sensor which caused further issues, or simply a power surge. Current cause is unknown.

For the past 3 to 6 months I've been hearing a gear backlash sound while using the adaptive cruise control when it would slow down for a car in front of the vehicle then when it would start to speed up. Brought the vehicle to the dealership on October 20th, 2025. They said that the sound is normal and there's a service bulletin that says its normal in other Chevy models. Then on November 28th, 2025 I was driving home, turn right at a light, and started to accelerate. Then I heard the same backlash noise as before then the check engine light came on with the oil light. I pulled over immediately and turned off the engine just to see all the oil spilling out of the engine compartment onto the ground and white smoke. Got it towed to the dealership and they told me that "the engine had multiple components fail inside it and that I need a new engine assembly." Currently the engine is still in the vehicle awaiting a new engine assembly what is currently on backorder with no expected arrival time.
